Benefits of technology
This patent aims to provide a solution for safely protecting power electric cables during a discharge process. The technical effects of this invention are that it ensures that the power electric cable is more secure and can be protected even if there is a false recognition of the allowed current value of the cable by equipment. This control method based on the specific signal ensures that the electric power cable is managed effectively and safely during the discharge process.
Problems solved by technology
However, no technique is known that concerns a limit of discharging current when discharging from the vehicle electric storage device to the external electric load.
Further, there is no art which discusses in detail how to notify a “current rating (permissible current value) of an electric power cable when discharging” to the vehicle control unit.

Embodiment Construction
[0071]A vehicle according to an embodiment of the present invention will now be described with reference to the drawings. The vehicle is applied to a discharge system. The discharge system is a system which supplies an electric power to an external electric load (which may include an external electric storage device) from a vehicle (on-board) electric storage section. This discharge system may be referred to as a “charge-discharge system”, since this discharge system has a function of a “charge-system, which can charge the vehicle electric storage section using an electric power supplied from an external power supply (which may include the external electric storage device).” Further, the vehicle electric storage section may include a “vehicle (on-board) electric storage device which is mounted on the vehicle and can be charged with (using) an electric power supplied from the external power supply (and a generator mounted on the vehicle)” and a “generator (electric power generating a...

A vehicle 10 according to an embodiment of the present invention is applied to a charge-discharge system CDS. The charge-discharge system includes the vehicle 10, an electric power cable 20, a plug-in station 30, a HEMS 40, and a commercial power supply 50. In a state where the connector 21 of the electric power cable 20 is connected with the inlet of the vehicle 10, an electric power is discharged / supplied from the vehicle electric storage device 11 to an external electric load (e.g., external electric storage device 41). Further, the vehicle electric storage device 11 is capable of being charged by the external power supply 50 through the electric power cable 20. A control device 12 of the vehicle 10 obtains / detects a permissible current value of the electric power cable 20, based on a specific signal (control pilot signal) which is transmitted through a CPLT terminal of the connector 21 before it starts the discharge to the external electric load from the vehicle electric storage device 11.
Description
TECHNICAL FIELD[0001]The present invention relates to: a vehicle having an electric storage section which can be discharged by supplying an electric power to an external electric load connected with the electric storage section through a electric power cable; a discharge system including the vehicle and the electric power cable; a method for controlling discharge of the electric storage section; and an equipment external to the vehicle used in the discharge system.BACKGROUND ART[0002]Conventionally, there has been known a charge-discharge system, which can charge an electric storage device mounted on a vehicle with (by) a power source (supply) external to the vehicle, and which can supply an electric power from the electric storage device mounted on the vehicle to an electric load external to the vehicle (including an electric storage device external to the vehicle, and the like). Supplying the electric power from the electric storage device mounted on the vehicle to the electric lo...
